Definitions
- the present invention relates to the use of partially known N-alkylated 1,4-dihydropyridinedicarboxylic acid esters as antiatherosclerotic medicaments, in particular their use for restenosis prophylaxis after angioplasty and vascular surgical measures.
- N-alkylieite 1,4-dihydropyridinedicarboxylic acid esters of the general formula (I) N-alkylieite 1,4-dihydropyridinedicarboxylic acid esters of the general formula (I)
- R 1 represents hydrogen, nitro, cyano, trifluoromethyl, trifluoromethoxy, halogen or methyl
- R 2 represents hydrogen, halogen, nitro, hydroxy, trifluoromethyl or methyl
- R 3 represents hydrogen or cyano
- R 2 and R 3 together form a condensed benzo ring
- R 4 and R 5 are the same or different and represent straight-chain or branched alkyl having up to 8 carbon atoms, which is optionally substituted by alkoxy having up to 4 carbon atoms,
- R 6 represents straight-chain or branched alkyl having up to 6 carbon atoms or cycloalkyl having 3 to 7 carbon atoms
- 1,2-Trimethyl-4- (4-trifluoromethylphenyl) -1, 4-dihydropyridine-3,5-dicarboxylic acid dimethyl ester and 4- (4-chloro-3-trifluoromethylphenyl) -1-cyclopropyl-2 are particularly preferred , 6-dimethyl-1, 4-dihydropyridine-3,5-dicarboxylic acid dimethyl ester in the control of atherosclerosis, in particular for restenosis prophylaxis after angioplasty and vascular surgery.
- the compounds according to the invention thus show an unforeseeable, valuable pharmacological spectrum of action.
- the compounds according to the invention inhibit smooth muscle cell proliferation.
- Vascular wall injuries lead to neointimal cell growth and consequently to a narrowing of the free vascular lumen. This process is the main cause of restenosis problems after vascular opening measures, such as percutaneous angioplasties, endarterectomies or bypass operations.
- the compounds according to the invention can therefore be used in medicines for the treatment and prophylaxis of residual enosis, e.g. after angioplasty and vascular surgery.
- the compounds according to the invention can also be used for the treatment of atherosclerosis.
- a balloon catheter is introduced into the carotid artery, this is inflated and the inside of the blood vessel is injured by moving the catheter [Clowes A.W., et al., Lab. Invest. Vol. 49, No. 3, p. 327, 1983].
- This damage causes neointimal smooth muscle proliferation, which cause stenoses.
- the extent of the vasoconstriction in the animals is determined after approximately 2 weeks by histological processing of the blood vessels by measuring the area of the proliferation tissue on vascular cross sections.
- the compounds according to the invention surprisingly significantly inhibit the vascular constrictions, as can be seen from the table below.
- the new active ingredients can be converted in a known manner into the customary formulations, such as tablets, dragées, pills, granules, aerosols, syrups, emulsions, suspensions and solutions, using inert, non-toxic, pharmaceutically suitable excipients or solvents.
- the therapeutically active compound should in each case be present in a concentration of about 0.5 to 90% by weight of the total mixture, ie in amounts which are sufficient to achieve the dosage range indicated.
- the formulations are prepared, for example, by stretching the active ingredients with solvents and / or carriers, optionally using emulsifiers and / or dispersants, e.g. if water is used as the diluent, organic solvents can optionally be used as auxiliary solvents.
- the application is carried out in the usual way, preferably orally or parenterally, in particular perlingually or intravenously.
- solutions of the active ingredient can be used using suitable liquid carrier materials.
